APPARATUS FOR FILLING RUBBER TIRES WITH VISCOUS LIQUIDS.'

Specification of Letters Patent..

Patented Bec. 28, i909.

Application filed .Tuly 30, 1909. Serial No. 510,355.

The invention relates more particularly to heating, mixing, and injecting mechanism for preparing and introducing a liquid or viscid composition into a rubber tire, said material comprising suitable ingredients suitably prepared in a main charging vessel and, when in proper condition for ejection for the purpose of filling the rubber tire,

having introduced and incorporated into it a hardening agent adapted to quickly set 'and harden the material when it reaches and has filled the rubber tube or tire, forming a yielding or elastic body providing a resilient tread for the tire. For the purpose of properly introducing and impregnating the prepared material withl this hardening or setting agent, l provide an independent auxiliary charging vessel for receiving and containing the hardening agent, said auxil-l iary charging vessel being in valved com munication with the air inlet pipe leading to the main charging vessel and having a discharge pipe intersecting the charge outlet pipe carrying the material from the main charging vessel, said discharge pipe' leading from the auxiliary charging vessel having a discharge stem or nozzle disposed at the median portion of said charge outlet pipe and extending in the direction of the iow of material therein whereby the hardening and setting agent is ldischarged in the middle of the flowing 'material and is thus thoroughly incorporated therewith.

The invention also relates to'iniprovenients in agitator mechanism for mixing and pre-- paring the material in the main charging vessel.

With the. above mentioned ends in view, thev invention consistsin the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in one of its embodiments in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings, forming a part of this specification, Figure l is a side elevation of an apparatus constructed in accordance with this invention. sectional View, with the agitator mechanism in operative osition. Fig. 3, an enlarged detail view o one oit the tire filling nipples of the charge outlet pipe.

Similar numerals of reference 'designate like parts throughout all the ligures of th drawings.

The heating, mixing, and charging' vessel l, is provided with a bottom or base portion 2,- aud is mounted upon a pair ot supporting bars or pedestals 3. rlhe bottom and side walls of the vessel l, are jacketed as at 4, and after the material has been prepared the material is discharged through a charge outlet pipe 5, comprising, in the present in stance, a horizontally disposed portion and a vertically disposed portion 5, provided with a plurality of tire filling nipples 6, adapted to be suitably inserted and connected to the nipples 7, of the inner tubes (not shown) of the tires 8. As a means of keeping the. passages of the nipples 6 and 7, free of obstructions, rods 6a, may be mounted in packing poXes 6b, the rods 6a, being withdrawn from said passages while filling the tires as indicated in Fig. l, of the drawings. The outlet pipe 5, is provided with a 4valve 9, whereby said outlet pipe may be opened or closed, as desired. The filling material within the'vessel 1, is adapted to be heated by means of a gas burner. l0, disposed be neath the bottom or base portion 2, of the vessel, and the latter is adapted to be opened and closed by'means of a lid or cover 1l, carried upon a screw 12, said screw being mounted within and carried by a cross-head.

the other provided with a hooked headlSa,

adapted to take over the opposite supporting bar or pedestal 3, between the bearing nuts 14a.' This arrangement of the cross head or bar 13, enables the latter to be swung horizontally and outwardly away from the top of the vessel or kettle l, carrying with it the lid or cover 11, for the reception of the driving gear mechanism for driving the agitator stirring blades as shown most clearly in Fig. 2, of the drawings. The lid or cove-r `ll, lis provided with a resilient gasaetl l5, adapted to take over and rest upon the upper marginal edges 1a, of the vessel when the cover is secured down by means of the screw 12, whereby the vessel is hermetically `sealed for the dischargeof 5 the tire filling material by compressed air as hereinafter described.v

The aeitator mechanism comprises a driving shafty 16, surrounded by a sleeve shaft 17, said driving shaft 16, carrying a plu-l rality of stirring blades 18, and said sleeve shaft 17, carrying a blade frame 19, provided with a plurality of cross blades v2O. The upper portion of the sleeve shaft 17 `maybe supported in a cross arm 21, in the upper portion ofthe vessel and the lower end of the driving shaft 16, is preferably Supported in a bearing-clip 22 in the bott-om portion of the vessel above the outlet opening thereof leading to the charge outlet pipe 5. The upper end of the sleeve shaft 17, is provided with a dog 23', and the upper end of the driving shaft 16,-is provided with a dog 24, said'dogs being adapted to be en gaged and driven in opposite directions by the mechanism hereinafter described, whereby the stirring blades 18, and cross blades 20, will always be oppositely rotated, but by reason of the relative disposition and inclination vof said blades the material will in the mixing operation be either worked downwardly toward the bottom of the vessel.

or upwardly therefrom. according to the direction in which the agitator blades are revolved.

The driving mechanism for drivin vthe 4agitator may be supported on a pair o supportinv beams 25, and comprises 'a horizon- 4 vtal driving shaftl 26,v mounted in bearing brackets 27, and preferably provided at one 40 end with a 'cone-pulley 28,'carrying a suitable belting communicating with a suitable source of power. A gear supporting frame 29, is pivotally mounted on the ends of the driving shaft 26, and is provided at its outer en d with a bearing head'29, carrying a bearing-sleeve-head 30, and an integral bevel gear 30a. The bevel gear 30a, is provided with a dog 31, adapted to engage the dog 23, of the sleeve shaft 17, said bevel gear receiving its motion by meshing with a gear 32, carried on a driving shaft mounted in the gear supporting frame 29, said driving shaft being provided at its rear with a second gear 33, meshing with a gear 34,' on the-horizontal driving shaft 26. A driving shaft 35, is mounted in the hearing sleeve head 30, and is provided at its upper end with a gear 36, meshing with the gear 32. The lower end of the driving shaft 35, is provided with a dog 37, adapted to engage with the dog 24, on the driving shaft 16, and by reason of the arrangement of the gears as above described it is obvious that the stirring blades 18, on the driving shaft 16, will be revolved in an opposite direction te that of the cross blades 20, carried by the sleeve shaft -17 and the arrangementof the agitator blades and gearing as above described enables the material to be mixed as desired.

The material when properly prepared is preferably ejected or discharged from the vessel 1, by means of compressed air, the air compressing mechanism preferably comprisA ing an ordinary air-compressor 37, provided 7 with an outlet pipe 3S, discharging into an yair compressionatanlr 39, said air compression tank being preferably provided with a gage 40, and communicating with the upper portion of the heating, mixing, andl charging vessel 1, by means of an inlet pipe 41, provided with al valve 42.

The hardening and setting agent is preferablystored in aseparate auxiliary charging vessel 43,-provided at its upper end with va valved inlet pipe 44, intersecting said air inlet pipe 41, and provided at its lower end Sfr vwith a valved disch-arge duct or pipe 45, in-

tersecting the charge outlet pipe 5, said d1scharge duct or pipe 45terminating'at its lowerv end in a discharge stem or nozzle 45, disposed at the median portion of said charge outlet pipe 5, and extending in the direction of the flow of the filling materialtherein, whereby the hardening and setting agent is discharged in the middle of the l stream of outfiowing filling material thereby thoroughly impregnating the latter with l the hardening and setting agent just prior to the entrance of the fillingmaterial into 10o the rubber tires.
